brucestout Boris Behncke • 6 hours ago.....or perhaps to phrase the question more simply: is the gas content of the magma entering the system more or less constant or does it vary? And does this variation explain the different phases or, conversely, are the phases merely a variation due to the eruption dynamics (foaming/degassing -> effusive activity).

excellent question!

question remain unanswered, and even excellent explanations about mechanism of origin of lava fountains at wired.com (above cited)do not add clarity of. found here year ago interesting comment with Etna description, history and risks

...The main problem of Etna in the fact that it has no direct consequences of the eruption depends on its strength and that's why.Etna Volcano amazing - both the shield volcano and built on its top stratovolcano. I'll tell you the well-known platitudes, which are everywhere found in his descriptions. Who is more dangerous and are considered as a shield to the eruption of the large number of cracks on the slopes and sides of craters because they are lower, closer to human settlements and when they poured out more lava (whereas in the higher craters and lava is far less does not apply). But just know that in the history of the most severe consequences of its eruption brought the collapse of slopes and a bore explosive. The fact is that except for the fact that it and the stratovolcano and shield, Etna, plus time and a huge caldera - it consists of a large number of growing on each other buildings with each of them - on the basis of their common patterns of calderas - sooner or later must come down. Amazingly complex system! And out of this just turns out that may not even be a very large eruption could potentially be disastrous - though exactly where it started, what type of will take place and what will be happening at the same time with every part of this beautiful monster individually and collectively .Uf.I'm sorry so many words only to explain why me disturbs new cracks on the slopes : new cracks means more possibilities of colapses, caldera type events, etc I guess. A large eruption would cause such an effect, or perhaps it is ordinary, what we often see in Etna, this one does not know in advance that bad. However many researchers in recent years noted with alarm that the Etna significantly alter a well-known to us for the past three centuries the type of activity. Let's watch!

my 5 cents. we are seeing though tumultuous, but very short paroxysms with fountain lava. ie the amount of emitted lava light and gases under high pressure a lot. so much in the body big cavities. what it may bring, knowing the history of Mount Etna?

The submarine volcano is located 25 km NNE of the NE tip of Iriomote-jima and 35 km WSW of the northern tip of the island of Ishigaki-shima in an area with an estimated depth of 200-300 m.A major submarine eruption took place at this volcano on October 31, 1924.

It produced rhyolitic pumice rafts with an estimated volume of about 1 cu km that were carried by currents along both coasts of Japan as far north as Hokkaido. The largest pumice blocks exceeded 1 x 2 m in size, and the volume of ejecta places this poorly known eruption among the largest in historical time in Japan.

could that glow be an indication that the peak is getting very hot? perhaps so hot it could collapse? also, what is the what looks like erupting steam coming from the bottom right of the webcam? another vent?

I haven't been following this eruption too closely. are there more vents?

In Iceland seems to care seismologists from the office all the earthquakes suddenly ends (although the morning after coming to office also suddenly appear on the map - for all their absence in the office) And yet there is also seems something interesting going on:

it's Fremrinamur volcano [link to www.volcano.si.edu] Volcano Type: StratovolcanoVolcano Status: TephrochronologyLast Known Eruption: 1200 BC (?) Fremrinamur central volcano, NNE of Askja and SE of Myvatn lake, is a volcanic system that is being constructed over the basaltic Ketildyngja shield volcano. Associated fissure systems, including the Sveinar fissure, extend 130 km to the northern coast of Iceland. The Kerlingardyngja shield volcano to the south is also part of the Fremrinamur volcanic system and formed about 6000 years ago. Iceland's renowned Myvatn lake formed as a result of the eruption of the massive 70-km-long older Laxarhraun lava flow from Ketildyngja shield volcano about 3800 years ago.
